ATTACHMENT FOR STEAM-ROLLERS.

SPECIFICATION forming part of Letters Patent No. 743,336, dated November 3, 1903. Applibation filed January 4, 1902. Serial No. 88,402. (No model.)

T0 at whom it may concern:

Be it known that I, WILLIAM SALWAY, a citizen of the United States, and a resident of Winton Place, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Attachments for Steam-Rollers, of which the following is a specification.

The several features of my invention and the Various advantages resulting from their use conjointly or otherwise will be apparent from the following description and claims.

In the drawings makinga part of this specification, and in which similar letters of reference indicate corresponding parts, Figure 1 is a view in perspective of a machine constructed to receive my improvements and with which myimprovements are combined, my improvements being also illustrated by said machine.

Fig. 2 is a side elevation of the adjacent wheel and of certain details of parts of my improvements, the wheel being partially broken away to the better enable these details to be seen. Fig. 3 is a rear view of the machine and of my improvements with the following exceptions, viz: that the wheel at the left-hand side is nearly all omitted and that a part of the right-hand wheel is broken away to the better disclose certain parts belonging to my improvements. Fig. 4 is a side elevation of the locking-pin. Fig. 5 is a detail illustrating the preferred mode of holding the free end of the wire rope when the latter is out of use. Fig. 6 is asectional detail of the said means for holding the free end of the wire rope to the pulley. Fig. 7 is an elevation of the hook and a section of the nut to carry into elfect the fastening of the free end of this rope. Fig. Sis a plan view of the rear end of the machine, showing the preferred means for holding the shives for guiding the wire rope and the mode of connecting such means to the rear of the machine. Fig. 9 is an outside elevation of the driving-wheel, which is on the left hand of the machine, a portion of which wheel is shown at the left in Fig. 3. Parts of the wheel in this Fig. 9 are broken away to the better show other portions of the wheel and that discal piece or wheel behind the driving-wheel which is fixed to the driving-shaft. Fig. 10 is a view at the rear edge of the wheel shown in Fig. 9. Parts of the wheel and of the tank are broken away to show the parts beyond. The hub of the driv- E indicates conventionally the mechanism which operates the forward wheels F and includes the chains F Such mechanism is for the most part located on the other side of the engine and is not seen; buta wheel E for causing such mechanism to operate said wheels B through the mechanism of the chains F is shown.

G indicates the driving-wheels, preferably provided, as shown, with a broad peripheral tread. Hindicates the axle or shaft on which said wheels are concentrically located and whereby they may be driven. The wheels are connected to this shaft H in such a manner that they can be unlocked therefrom or locked thereto in a prompt and expeditious manner. A preferred mode for accomplishing such locking and unlocking is as illustrated--namely, fixed to the wheel G is a hub-piece G This hub-piece and its wheel are loose on the shaft H. Fixed to the shaft H is a crank-piece H preferably of a discal form, as shown. There is a hole, as G in the hub-piece G and a seriesof holes, as H in the discal piece H These holes in discal piece H are set in the line of a circle, and

each will successively come into alinement with the hole G in the crank-piece G as the axle H audits discal piece H are rotated or as the crank-piece G is revolved. A lockingpin H is present and when passed through' ICO hole of the hub-piece G without much rotation of the shaft. Thus the wheel G can be locked to the shaft without much rotation of the shaft H or of the wheel G, which may have first been locked to the shaft. There is a locking-pin H for the driving-wheel G and discal or crank piece on the one side and another locking-pin for the driving-wheel and its adjacent discal piece or wheel on the other. While I could make both of these discal pieces pulleys, it is usually unnecessary to do so. I therefore make one of these discal pieces as a pulley or spool and provide it with a peripheral groove H Thus in the illustrative drawings I provide thed iscal piece H with such peripheral groove H The other or opposite discal piece L H I utilize as a gear and adapt it to engage with gear operated by the engine. As such engine-gear is old and well known, I omit further mention of it. To this pulley H Iduly connectone end of a wire rope or chain J, preferably the former and of a size convenient to be wound on this pulley H within the groove of the latter. In connection with this pulley H, I provide guides of a novel adaptation, application, and location to accomplish the objects for which the pulley and rope are designed.

K indicates a bar of iron Whose free end is extended out beyond the plane of the ad jacent side of the coal-box, substantially as shown in Fig. 3. The other end is fixed to a rear portion of the machine, preferably, as shown, by the bolt L andby the bolt L K is a. second bar parallel to the bar K, and

one end is secured to the machine, prefer ably by the bolt L, and its free end extends out above the bar K. These bars are further secured by a link N, which is secured to the bolt L and is secured to the bars by a bolt N. The free ends of these bars are secured together by a bolt L The attachment of these bars K and K to the flanges L and L and by the linkN holds the latter firmly in the position shown. These flanges L and L are fixed to the box 0. Between these bars K and K are located two shives or guide-pulleys M M, preferably grooved, as shown. These shives are duly journaled in the bars K and K and are respectively supplied with oil-boxes M M whereby they are duly lubricated.

The mode in which my invention is operated is as follows: The road and traction eugine heretofore described is caused to propel itself to any place desired. The great wheels G are utilized for packing down and smoothing the rough parts of roads and other places, as may be desired. The traction-engine can be employed for traction purposes by connecting the thing which is to be drawn or dragged by a chain or other suitable connection to the link R at the rear end of the coalbox G. The engine being started forward, it

, regularly.

ward or backward movement of the engine is wholly unnecessary and undesirable. The first of these is when the movement of the engine would carry it over ground which ought not to be crossed by the engine or when the way is barred by rocks, marsh, or other impediments, so that the engine could not proceed; In this case whether the engine when under movement would or would not have traction-power enough to draw along the thing to be drawn it is evident that it must not be moved. The second of these cases is when the resistance of the thing to be drawn is greater than the traction of the engine can overcome. In both of these cases my invention becomes essentially necessary. I then operate my invention as follows: I block the great wheels G. I withdraw the locking-pin H from the pulley H and on the other side also disconnect the wheel G there from that end of the shaft or axle H. The pulley H is then rotated, usually by the engine, and the wire rope J unwound until enough of it has been paid out to enable the free end of it to be hooked or otherwise connected to the article to be dragged or drawn. Such connection with the latter article having been made, the engine is set in motion and the pulley H rotated so as to-gradually wind up the wire rope J, This it will do with great power and effect. I am enabled to plow therewith to a great depth in a macadamized street or equally rocky and hard soils. As the wire rope is wound up it is guided between the two shives. When the plow or other thing to be drawn or dragged is drawn to or near to the engine or as far as desired by the wire rope and it is desired to repeat the operation, the free end of the wire rope is drawn back, thereby unwinding the rope from the pulley. When it is desired to return the plow or similar implement to its first position at the end of the wire rope, (unwound,) I usually employ a horse to return said implement. It is at such times that the brake I will now describe becomes of special utility. This'brake consists of a shoe P and a lever P pivotally fulcrumed at P to the machine by a removable fulcrum. Thus the brake can be removed when not in use. The lever is bent at P so as to duly bridge the pulley H The shoe P bears against the side of the pulley H near the periphery of the latter. When the wire rope is being drawn out too fast, which is particularly the case when the horse feels skittish or full of life, an application of the brake to the pulley H serves to hold him back and compel him to move quietly and After the work to be performed by the pulley H and wire rope, &c., has been accomplished the wire rope is wound up upon the pulley and the free end of the rope is fastened to the pulley.

The means for fastening the pulley constitute still another feature of my invention and are as follows: I provide a hook S, having a shank 8*, the latter having on its free end a screw-thread S The outer rim of the pulley ICC IIO

is provided at convenient intervals with holes H After the wire rope J has been wound upon the pulley it becomes desirable to fasten the loose end of the rope. Thereupon the shank of this hook S is passed through that hole H of the pulley-rimwhich is nearestthe end of the rope. The end part of the rope is placed in this hook. The latter is then pressed toward the pulley. The free end of the shank now projects inside the rim, and the nut S is now screwed thereon. Thus the ropes end isduly held. The revolution of the pulley as the steam-roller is moved and the axle H revolves will not unwind the rope. When it is desired to use the rope, as before mentioned, I unscrew the nut, withdraw the hook, and loose the ropes end from the latter. Wherever the term wire rope is used I desire it to be read as standing for chain or other suitable flexible means of connection.

What I claim as new and of my invention, and desire to secure by Letters Patent, is-
